JAMES H. BOYE AND ERIK S. HAGEN, OF CHICAGO, ILLINOIS, ASSIGNORS TOJAMES H. BOYE MANUFACTURING COMIPANY, OF CHICAGO, ILLINOIS, ACORPORATION OF ILLINOIS.

Application filed June 22, 1916.

To all whom it may concern Be it known that we, JAMES 11. Born and ERIKS. HAGEN, citizens of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Sash-Holding Devices, of which the following is aspecification.

This invention relates to sash-holding or supporting devices of thatgeneral type wherein a roller is carried by one of the relativelysliding parts comprising the sash and its guide groove and engages thevertical wall of the other part, the roller being so controlled that itmay turn freely during the upward movement of the sash but is lockedagainst rotation in the opposite direction during the downward movementof the sash, and is further provided with spring means for forcing itagainst the vertical surface over which it rides with sufficientfriction to prevent the sash from dropping under its own weight, butpermitting the sash to be readily drawn downwardly. Sash holders orsupports of this general character are designed to do away with theusual sashbalancing weights, but, of course, lack one function of thelatter which is to counterbalance the weight of the sash during thesash-lifting movement.

The principal object of our invention is to provide an improved andsimplified sashholder or support of the characterspecified which shallbe economical to manufacture, easy to apply, shall not require themortising of either the sash or the frame for its application, and shallbe easily and conveniently adjustable to vary the spring pressure of theroller as required.

Other objects and advantages of the invention will be apparent as thesame becomes better understood by reference to the following detaildescription taken in connection with the accompanying drawing wherein wehave illustrated a practical and preferred embodiment of our inventionwhich has been found to efficiently accomplish the stated purposes andobjects thereof.

Referring to the drawings, Figure 1 is a fragmentary elevation of awindow frame and sash illustrating the application of our invention, theguide-groove of the lower sash appearing in section; Fig. 2 is a topplan vlew of the lower sash to which our im- Specification of LettersPatent.

proved-holder is applied, the guide-groove and upper portion of theholder appearing in horizontal section; Fig. 3 is a longitudinal sectionas seen on the line 33 of Fig. 2, and Fig. 4 is a sectional view takenon the line H of Fig. 8.

Referring to the drawing, 6 designates the upper horizontal sash rail ofa lower window sash, and 7 designates the usual vertical groove orchannel in which the vertical side of the sash is guided.

8 designates a channel-shaped casing or housing that rests upon theupper sash rail 6 and is preferably secured in place by a cover member 9having vertical walls 10 that overlap the side walls of the casing 8 andterminate in horizontally disposed flanges 11, through holes in whichfastening screws 12 enter the sash rail 6. The casing 8 is provided atits end adjacent to the guide groove 7 with a pair of parallelupstanding walls 13 that are preferably oontinuations of the side wallsof the casing S; and through the upper end of the walls 18 is passed apin 14-, on which latter, and between the walls 13, is pivotallysuspended a roller-supporting hanger comprising parallel side walls 15and a connecting rear wall 16. In and between the forward portions ofthe side walls 15 of this hanger is j ournaled a roller 17. Lying withinthe casing 8 is a coil spring 18, the forward end of which abuts againstthe lower end of the rear wall 16 of the roller hanger, while its rearend is engaged, through the intermediary of a swivel cap 19 with anadjusting screw 20 that passes through the rear wall of the casing 8 andhas threaded engagement with a plate or block 21 just inside said rearwall. Preferably, and as herein shown, the extent of forward swing ofthe roller and its support under the impulse of the spring 18 is limitedby a lug 22 struck inwardly from one of the side walls 13 of the casingand adapted to engage with the lower edge of one of the side walls 15 ofthe roller hanger. Between the periphery of the roller 17 and the rearwall 16 is interposed a roller 2", which, by reason of the fact thatsaid periphery and rear walls 16 are upwardly di vergent and downwardlyconvergent, as clearly shown in Fig. 3, operates to permit free rotationof the roller 17 in a counterclockwise direction, viewing Fig. 3, butacts as a look, after the fashion of a roller clutch, to prevent theturning of the roller 17 in the reverse or clockwise direction.

The device, constructed as shown and described, is mounted on the sashrail 6 in the manner clearly shown in Fig. 1, with the roller 17 inengagement with the bottom wall of the guide groove 7. The adjustingscrew 20 is then turned so as to press the roller 17 against the bottomwall of the groove 7 with sufficient force to support the sash inelevated position by reason of the friction between the periphery of theroller 17 and the bottom wall of the groove 7. In other words, thisfriction is slightly more than is required to counterbalance the weightof the sash.

In raising the sash, the roller 17 rolls freely on the bottom wall ofthe guide groove. When the sash is released and tends to drop, theroller 17 is instantly checked by the little roller 23 against rotationin the reverse direction, and the friction between the periphery of theroller 17 and the bottom wall of the groove 7 suffices to hold the sashraised. This friction may, however, be overcome and the sash lowered bythe application of a slight downward pull on the sash.

From the foregoing it will be evident to those familiar with this artthat we have produced a sash holding or supporting device that fulfilsthe several purposes or objects hereinabove stated in an efficientmanner. 7

Without, therefore, limiting ourselves to the precise details ofconstruction, which may be varied to a considerable extent withoutinvolving any departure from the principle of the invention, -we claim:

1. A sash support comprising a casing adapted to be secured upon the topof a sash rail, having upstanding side walls at one end thereof, acarrier, including a curved rear wall and parallel side walls pivotallysuspended between said casing side walls, a roller journaled in saidcarrier so as to project beyond the end of said casing, a locking.roller disposed between said first mentioned roller and the rear wall ofsaid carrier in position to wedge between said roller and said wall soas to lock the roller against rotation in one direction, and a springfor yieldingly swinging said carrier outwardly on its pivot.

2. A sash support, comprising an elongated fiat bottom casing adapted tobe mounted upon the top of a sash rail and provided at oneend withupwardly extending side portions, a roller carrier consisting of a backand side walls pivotally suspended between said upwardly extendingportions, a roller journaled in fixed bearings in said carrier, a springarranged in said casing to urge the lower end of said carrier outwardlv,and a gravity-actuated locking device loosely positioned in the anglebetween said roller and said back wall of the carrier for locking saidroller against rotation in one direction,

the axis of said roller being disposed out-' wardly of a vertical linethrough said carrier pivot and beneath said pivot so that a togglethrust effect is produced against the window frame groove when saidroller is locked.

3. A sash support, comprising a casing consistlng of a body member openat one end and having vertically extended side walls at said open endand a cover member having depending flanged s de walls adapted to besecured to a sash rail, a bodilymovableroller mounted in the open end ofsaid body mem-' ber between said vertically extended side walls, aspring in said casing tending to N force said roller outwardly of saidopen end,

an adjusting screw in the other end of's'aid body member for tensioningsaid spring, and means limit ng the rotation of said roller to onedirection.

4. A sash support, comprising a casing consisting of a bodv member openat one end and having vertically. extended side walls at said openendand a cover member having depending flanged side walls adapted. to besecured to a sash rail, a roller-carrier pivotally suspended from andbetween said vertically extended side walls, a roller journaled insaidroller carrier, a spring in said casing abutting at one end against saidroller-carrier, an adjusting screw in the other end of said casingabutting against the other end of said spring, and means limiting therotation of said roller to one direction.
